About EuroClonality

EuroClonality is a European scientifically independent foundation aiming to promote continuous innovation and standardization of laboratory diagnostics in hemato-oncology with a special emphasis on clonality testing and supporting quality control and education in laboratory diagnostics. EuroClonality developed and standardized novel multiplex PCR assays for detection of immunoglobulin (IG) and T-cell receptor (TR) gene rearrangements. These assays are now widely used for the diagnosis of lymphoproliferative disorders.

EuroClonality EQA Scheme

Together with the Biomedical Quality Assurance Research Unit of the KU Leuven, EuroClonality organizes an annual External Quality Assessment scheme. All laboratories working with the EuroClonality/BIOMED-2 multiplex PCR assays for detection of IG/TR gene rearrangements can join this EQA scheme to evaluate their performance.

Support and Protocols

EuroClonality and the EuroClonality-NGS Working Group also offer support to the diagnostic community via the Online Diagnostic Support Service for problematic cases in clonality testing with the EuroClonality/BIOMED-2 assays, a FAQ section on the use of these assays, and by providing protocols of IG/TR NGS methodology.

EuroClonality publishes Recommendations for Evaluation of B-Cell Clonality Analysis by Next-Generation Sequencing.

NGS-based clonality analysis is a powerful technique for the assessment of Ig clonality, but it has its specific pitfalls. EuroClonality developed a step-by-step approach to interpretation of NGS-amplicon–based assessment of clonality which will allow a reliable and reproducible interpretation of the results and will help to avoid overinterpretation. This is all published in a paper named: EuroClonality-NGS Recommendations for Evaluation of B-Cell Clonality Analysis by Next-Generation Sequencing: A Structured Approach with the DEPART Algorithm.
